ANSWERS MUST BE IN 3 DECIMAL PLACES 1. A 400-N weight starts down the incline of 30o with the horizontal with an initial velocity of 4m/s. Find the velocity of the weight after 10s if fk = 0.2 for the incline. 2. A 400-N body starts up the incline of 30o with the horizontal (fk = 0.2) with a velocity of 3m/s. How long must a 500-N horizontal force act on the body to increase its velocity to 8m/s? 3. A 400-N body starts up the incline of 30o with the horizontal (fk = 0.2) with a velocity of 3m/s. How far will the body travel while the force is acting?
4. You are pushing horizontally with a 300 N force on a box that is on an inclined plane as shown. The mass of the box is 30 kg and the incline is at a 25 degree angle off the Fapplied horizontal. The coefficient of kinetic friction between the box and the incline is 0.3, and the coefficient of static friction i 0.4. Assuming the box was at rest at t=0 when the force is initially applied, is the box moving up the ramp, down the ramp, or is it at rest after the force has been applied? 25⁰
A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp. What problem could occur if the coefficient of friction were too high? pur answer: Packages would go too fast and could break at the end of the ramp. Packages could slow down too quickly and stop before the end of the ramp. Packages could break the ramp because gravity would increase. Packages could bounce off the ramp because normal force would increase. Clear answer
Use the value of g = 9.80 [m/s^2]
9. Two blocks are positioned on surfaces, each inclined at the same angle of 58.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.66 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.460. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? 2.16 kg 9.99 kg 6.02 kg 3.06 kg

17. A child decides to take her cat on a walk, but the cat does not cooperate. The child pulls on the 2.5 kg cat with force of 20 N in a direction that is 30 degrees above horizontal, and the cat resists being pulled forward with a horizontal force of 15 N. How much force is the child pulling with in the horizontal direction (the direction the cat will move)? Your answer: 10 N O 17 N O 20 N O 600 N
